I am curious about what sharpeners (manual) you folks use? I am obsessive about a wicked sharp blade, but am constantly frustrated by chasing the "burr" from side to side. I have heard that stropping can cure this, but I don't want to pack a strope around with me. I have also read one of the posters speak of a convex edge. I have read some about that edge being useful, but how is edge retention and sharpness? I read that you can use a mouse pad and 1000 grit paper to get a convex edge??
